Description

Technical Field

[0001] The utility model relates to the technical field of thyristor crimping positioning and monitoring, in particular to a plate component crimping system which is convenient for accurate disassembly and assembly. Background Art

[0002] In the excitation control system, when the generator has non-inverting demagnetization and rotor overvoltage, it is often necessary to put in demagnetization resistance. The use of demagnetization resistance usually requires the conduction of the thyristor to form a circuit. In this process, multiple thyristors are usually required. At present, the degree of fit between the thyristor and the conduction plate during crimping installation mainly depends on the naked eye observation of the staff. The thyristor and the conduction plate are directly crimped to form a whole without any positioning treatment. This not only easily leads to low installation accuracy of the thyristor body, but also leads to its installation and fixation being not stable and reliable enough, and it is impossible to ensure that the thyristor and the conduction plate are tightly attached together, thus affecting the conduction effect. Based on this, in response to the above problems, we have designed a plate component crimping system that is easy to disassemble and assemble accurately. Utility Model Content

[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] like Figure 1 , Figure 2 As shown, the utility model provides one of the embodiments: a plate device crimping system that is easy to disassemble and assemble accurately, comprising: a central control unit, a positioning monitoring unit and a crimping unit; the positioning monitoring unit is fixedly installed at the crimping unit, the positioning monitoring unit is wirelessly connected to the central control unit, and the central control unit is electrically connected to the crimping unit; wherein the positioning monitoring unit comprises: a position sensor; the position sensor is fixedly installed at the crimping area and the fixed area of ​​the crimping unit, and is used to monitor the relative position of the thyristor and the conduction plate, the position sensor is wirelessly connected to the central control unit, and also includes a display unit, the display unit is used to display the monitoring data of the positioning monitoring unit, and the display unit is electrically connected to the central control unit; also includes an alarm unit, the alarm unit is specifically an audible and visual alarm, the audible and visual alarm is respectively fixedly installed at the display unit and the crimping unit, and is used to execute audible and visual alarm, and the audible and visual alarm is electrically connected to the central control unit; the central control unit is specifically a PLC controller.

[0018] More specifically, the crimping unit is a crimping machine, which includes a crimping head and a fixed base; the crimping head is the crimping area of ​​the crimping unit, the fixed base is the fixed area of ​​the crimping unit, and the crimping machine is electrically connected to the central control unit.

[0019] In the specific application of this embodiment, the staff manually checks the sensor status after turning on the system. Before performing the crimping of the thyristor and the conduction plate, the staff first uses the position sensor to detect whether the thyristor and the conduction plate are aligned. If misalignment is detected, the staff adjusts the crimping machine to the correct position according to the position sensor monitoring data displayed in the display unit. After alignment, the PLC controller controls the crimping machine to perform crimping, and monitors the pressure in real time through the pressure sensor to ensure that it does not exceed the preset range. After the crimping is completed, the resistance value is measured by the contact resistance sensor, and the staff judges the contact quality according to the resistance value displayed on the display unit. If the resistance value does not meet the standard, the staff controls the crimping machine through the PLC controller to readjust or re-press.

[0020] In this embodiment, the positioning monitoring unit further includes: a pressure sensor; the pressure sensor is fixedly installed at the crimping area of ​​the crimping unit to monitor the crimping force of the crimping unit, and the pressure sensor is wirelessly connected to the central control unit.

[0021] During implementation, the pressure sensor is embedded in the crimping head of the crimping machine and directly contacts the crimping area to monitor the pressure during the crimping process in real time, ensuring that the pressure is within a safe range and preventing damage to components due to excessive pressure.

[0022] Furthermore, the positioning monitoring unit also includes: a contact resistance sensor; the contact resistance sensor is fixedly installed at the contact surface between the thyristor and the conduction board, and is used to monitor the contact resistance. The contact resistance sensor is wirelessly connected to the central control unit.

[0023] In implementation, the contact resistance sensor is fixedly installed near the crimping contact point, and a special sensor structure can be used to adapt to the mechanical parts. This embodiment takes the following specific sensor structure as an example. The sensor head of the contact resistance sensor is designed to be ring-shaped, which can be wrapped around the crimping point. It does not directly contact the crimping core area, but can closely monitor the resistance of the contact area. Through the ring design, the resistance can be measured from multiple angles to provide more comprehensive data; in addition, the contact point of the contact resistance sensor can be made of highly conductive material and have a certain degree of elasticity, which can slightly contact the surface of the conductive plate. The elastically designed contact point can reduce the physical impact on the crimping parts while ensuring sufficient contact area to obtain accurate resistance readings. If the contact resistance sensor exemplified by this embodiment is installed near the pressure head of the crimping machine.

[0024] Each sensor used in this embodiment is a miniaturized wireless sensor, which can be installed in the corresponding area by a detachable connection method such as bonding, which can help save space. The integrated installation also reduces external wiring and improves the stability and anti-interference ability of the system. It can be understood that the structural features of the contact resistance sensor provided in this embodiment are only used as an example. In actual application, other structures that can also achieve the corresponding effect can also be used for design.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
